Abstract

The uncertain existence and insufficient information of underground structures, such as pipe lines and cable tunnels, is causing many problems related to route plan, design, construction of new underground structures. The theoretical equations that is able to predict the location, size, and direction of underground structures through electric field analysis are suggested at the previous study (Ryu., 2015). Three field tests were performed for predicting the location, size, and direction of underground structures and the existence and size of sink-hole. Prediction results were reflected at the design and follow-up measures were performed.

관로, 전력구 등 지하매설물의 불투명한 존재여부 및 부정확한 정보로 인해 신규 지하매설물의 계획 노선, 설계, 시공에 많은 문제를 야기시키고 있다. 이에 Ryu(2015) 등은 전기장 해석을 통해 지하매설물의 크기, 위치, 방향 등을 예측할 수 있는 식을 제안하였다. 3개의 현장에 적용하여 싱크홀 존재 여부 및 크기와 지하매설물의 위치, 크기, 방향을 예측하였으며, 예측된 결과를 토대로 설계에 반영되고 후속 조치가 수행되었다.
